Magnetic PowderSimilar in tone to our standard black latent print powder, Black Magnetic Powder is recommended for use in dusting glossy papers (such as magazine covers), tissue paper, rough or polished wood, leather, plastics, glass, and rubber. It works exceptionally well on plastic baggies after they have been treated with cyanoacrylate esters (superglue fumes). Powder is packaged in wide mouth jars for easy access with a magnetic applicator.
